So, this would be a common circle question. 

First, 20 degrees from a circle's curcumference would be 20/360, which is 1/18.

This means that the length of the arc of AB should be 1/18 of the circumference.


The formula for the circumference it 2pi*r

2*pi*27=54pi

54pi* 1/18= 6 pi

Which is the equation of a line that passes through the points (1,4) and (-1,1)
horsena [70]

Answer:

The equation of the line is y = 3/2x + 5/2

Step-by-step explanation:

To find the equation of this line, start by using the two points with the slope formula to find the slope.

m(slope) = (y2 - y1)/(x2 - x1)

m = (4 - 1)/(1 - -1)

m = 3/(1 + 1)

m = 3/2

Now that we have the slope, we can use that and either point in point-slope form to find the equation.

y - y1 = m(x - x1)

y - 4 = 3/2(x - 1)

y - 4 = 3/2x - 3/2

y = 3/2x + 5/2
